As peer-to-peer computing finally reaches a critical mass, it triggers changes in the IT landscape that traditional network infrastructures, based on centralized, client/server topologies, cannot manage. Consequently, the ad hoc, self-organized, and loosely controlled nature of peer-to-peer networks needs to be supported by a new coordination layer representing the interests of the user. In ord...

In this paper, the authors analyze and compare two airship configurations for the Elettra Twin Flyer prototype, an innovative airship concept which is remotely-controlled and intended for monitoring, surveillance, exploration and reconnaissance missions. The aim of the comparison is to determine the most appropriate solution in terms of performance, cost and maneuvering capabilities. In particu...

Background and aims: An increased occurrence of anti-Saccharomyces cerevisiae antibodies (ASCA) is reported in unaffected members of families with Crohn’s disease. Whether ASCA is a familial trait due to genetic factors or is caused by exposure to environmental factors is unknown. To assess the genetic influence of ASCA we studied its occurrence in a twin population. Patients and methods: ASCA ...

This article is a scientific interpretation of Vedic, Upanishadic, Tantric and Puranic conceptions of Cakras & 'Ardhanareeshwara' in the light of modern neuro psychological research. It also attempts to make striking similarities between the 'twin brain' and the concept of 'Ardhanareeshwara' and to show how the Ancient Indian sages conceptualized this 'two in one', brain reality long ago what n...

We investigate a time-domain implementation of generalized phase-conjugated twin waves which we call conjugate data repetition. A theory based on time-domain perturbation analysis explaining the mitigation of nonlinear effects is provided, and the concept is evaluated using numerical simulations. Compared to PM-QPSK at the same channel bit rate, the single-channel transmission reach in a conven...

Smart city digital twins can provide useful insights by making effective use of multi disciplinary urban data from diverse sources. Whilst these new information that helps cities in decision making, verifying the authenticity, integrity, traceability and ownership across various functional units have become critical characteristics to ensure is an authentic trustworthy source. However, are rare...

AIM Neuropathological examination of both individuals in a monozygotic (MZ) twin pair with Alzheimer's disease (AD) is rare, especially in the molecular genetic era. We had the opportunity to assess the concordance and discordance of clinical presentation and neuropathology in three MZ twin pairs with AD. METHODS The MZ twins were identified and characterised by the University of Washington A...

For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...
